Sigma can make a hit with some affordable super-tele lenses 400/4 would be great, 500 5.6 would be nice. They can renew 300 2.8 and 500 4.5, actually smaller and lighter 400/4.5 may not be a bad idea too.50-500, 150-500 and 120-400 zooms could be improved.

I was looking at the Canon 24mm 1.4 for some event work but now i will definitely wait for the Sigma. It's gonna be hard to beat the Canon 24L but hell, if its under 1k and as good as the 35 consider it purchased.

What will Sigma deliver lenses too when Canon and Nikon have filed for Chapter 11 due to the very poor lens sales

their own camera line...

That's just what I was going to speculate. Maybe they've improved their foeven stacked photosite technology and are going to bring out a new camera with it. Maybe that's why they've been creating these significantly higher quality lenses and lens-mount change program in preparation for a new camera of their own.

I'm gonna take the flip side of this --- if sigma puts all their effort into lenses, they keep their focus (pun) on glass and that leads to better glass at a lower cost. I am happy with this idea, keep making kick ass new glass that makes me say I may want one (i have been considering a 24mm prime, and have been tempted by the 35, but a 35 while awesome just isn't what i am looking for (prime trilogy- 24 - 50 - 85). This won't drive either canon or nikon out of the lens game, but ----hopefully it will make them flinch on pricing, or, step up their game to make the extra cost more enticing.

Sigma has definitely stepped up their game recently.I am currently on the fence to buy the 18-35 1.8, what holds me back is the hope for some further price drops when the early adopters have been fed.

The 120-300 2.8 OS is definitely something I would love to have, both for focal length (my longest serious lens is the 70-200 F4 IS, not counting the Tamron 28-300 VC, which has been setting on the shelf for a while now... ) and for speed, but unfortunately at 3+kg it is a tad too heavy and at 3k€ also too pricey for a hobbyist.

What really is missing is a serious contender for the Canon 100-400, i.e., a moderate zoom-range, only a f5.6 aperture at the long end, but weight < 1500 grams and price <1500€. And of course this lens should continue the trend of Sigma's latest offerings - awesome image quality already wide open. Neither the old 120-400 OS, the 150-500 OS, nor the 50-500 OS are good enough in my book to seriously challenge the ancient Canon 100-400. If Canon finally announces a successor, it will probably be 20% better and cost twice as much, which finally moves it out of my hobbyist budget. That will definitely leave a huge gap for Sigma to fill.

Does anyone know about the sales numbers of 24/50/85/135 primes, i.e. why would Sigma add a 24mm next and not rival mediocre-sharp Canon's 50L with a 50mm update of their own or release contenders to the rather expensive 85L/135L?

My guess is because 24mm @ 1.4 has the largest vacancy in the market place. Right now it's just the Canon if you want autofocus, and the Rokinon didn't get good reviews at all compared to their 35mm.

50mm - They're probably working on it, but until they get it right are content with their current 50mm. Like i said, the 50mm prime market has a lot more competitors than the 24mm. It's definitely "ripe for the taking" given the optical performance of the current primes, but it's gonna be a harder sell to non-professionals (the majority of the market) who are content with the current Canon 1.4.

85mm - Their current 85mm 1.4 is already pretty darn good, and its the only auto-focus 85 1.4 on the market. Updating it probably won't bring in that big of revenue jump, so it's further back on the to-do list.

135mm - The canon is already pretty cheap, so I'm sure they're waiting to perfect OS or a > f/2 design to ensure it can compete with the ~$800 name-brand Canon.

The market is just more open for fast 24mm prime.

Sigma needs to build up its reputation before it goes head-to-head with the entire Canon lineup. But it seems like they've got some fresh talent in both their engineering and business departments. A 24mm prime might not be the most popular length for the average photographer, but it's a favorite amongst pros. Plus, a 24mm is quite versatile on cropped sensors. And for video, it's a great length, especially with the proliferation of all these tiny sensors.
